Title: Signal encoding for transmission of multiple digital signals over single physical medium
Inventor: MUJTABA SYED AON
IPC: H03M5/16
Filed: 2000-07-21
Granted: 2004-05-25
Abstract: Two or more digital signals are encoded using two or more respective line codes. The line codes are chosen in conjunction with the data rates of the digital signals such that the encoded signals are substantially orthogonal to each other in the frequency domain. As such, the two or more encoded signals may be combined and transmitted via a single physical medium with little or no interference. A transmitter for encoding and transmitting the digital signals contains line coders for encoding the digital signals and a combiner for combining the encoded signals for transmission via a single physical medium. A receiver for receiving and decoding the combined encoded signal contains filters for extracting the individual encoded signals and line decoders for decoding the individual encoded signals to generate the original digital data signals.

Abstract: A railway brake system (10) for a train includes a brake pipe extending along the train, a lead unit controller (29) generating a pneumatic control signal propagated along tho brake pipe, and at least one remote unit controller (25, 28). The remote unit controller preferably includes a brake pipe control valve, such as a relay valve (26), connected in fluid communication with the brake pipe (20) for selectively charging and exhausting the brake pipe, an air flow rate sensor (30, 31) for sensing air flow into the brake pipe during charging, a brake pipe pressure sensor (40) for sensing brake pipe pressure, and a processor (36) for detecting the pneumatic control signal from the lead unit controller based upon both the air flow rate sensor and the brake pipe pressure sensor. Accordingly, the sensitivity of detection is increased despite delayed operation of the relay valve, and while avoiding false indications. Multiple detection sensitivities may be used.  The detection may be used to cut-out the remote unit controller and idle down the locomotive, as when radio communications are lost. The detection may also be used for brake pipe continuity testing and/or to determine the relative position of the remote unit along the train.

Abstract: A method and system (10) utilize both the radio frequency (RF) and infrared (IR) parts of the electro-magnetic spectrum to locate subjects (i.e. objects and persons) within a tracking environment. The system includes a battery-operated, microprocessor-based badge (12) for each subject to be located. Each badge automatically transmits digitized infrared light signals to provide a fine determination of its subject's location. Each badge transmits RF and IR  signals upon actuation of a page request/alert push button switch (42) on its badge. The IR and RF signals are modulated or encoded with badge identification data, page request or alert notification data, and battery condition data. The system also includes ceiling or wall sensors in the form of IR (20) and RF (26) receivers, and a host computer (36). The locating method and system are particularly useful in hospitals to monitor the location of patients and/or critical equipment.

Abstract: A magnetomechanical EAS marker (20) includes a housing (22), a magnetostrictive active element (26) in the housing, and a bias magnet (56) mounted on the housing adjacent to the active element (26). Both the active element (26) and the bias magnet (56) are substantially planar metal strips. The length and/or surface area of the bia s magnet (56) is substantially less than the length and/or surface area of the active element (26). The reduction in the size of the bias magne t (56) relative to the active element (26) enhances reliable deactivation of the marker by increasing the resonant frequency shift obtain ed by degaussing the bias magnet. The increased reliability of deactivation is obtained without increasing the sensitivity of the marker, when in an active state, to variations in applied bias magnetic field.</SDOA B>

Title: Fault type selection system for identifying faults in an electric power system
Inventor: ROBERTS JEFFREY B
IPC: H02H3/28
Filed: 2001-10-19
Granted: 2011-02-08
Abstract: The fault identification system includes a first logic circuit which is responsive to conventional protective elements which recognize the presence of low resistance single line-to-ground faults for the A, B and C phases on a power transmission line. The first logic circuit includes a portion thereof for recognizing and providing an output indication of single line-to-ground faults, faults involving two phases and three-phase faults, in response to the occurrence of different combinations of outputs from the protective elements. A calculation circuit, when enabled, is used to determine the angular difference between the total zero sequence current and the total negative sequence current for high resistance faults when the protective elements themselves cannot identify fault conditions. The angular difference is in one of three pre-selected angular sectors. An angular difference in the first sector indicates an A phase-to-ground fault or a BC phase-to-phase to ground fault; an angular difference in the second sector indicates a B phase-to-ground fault or a C phase-to-phase to ground fault; and a signal in the third sector indicates a C phase-to-ground fault or an AB phase-to-phase to ground fault. A processor is used to determine which of the two possible for each angle determination is the actual fault type. An output indication of the actual fault type is then provided.
